    UP 
    Piston Seals are non-symmetrical lip seals of single-acting design.  The asymmetrical cross-sectional shape insures that the seal remains steady in the groove preventing tipping or twisting, resulting in excellent sealability and low-drift as well as low breakout force.  Double acting cylinders require tandem seals in separate grooves.

    E4
    profile is a non-symmetrical piston seal designed to seal both lubricated and non-lubricated air.  To insure that critical surfaces retain lubrication, the radius edge of the lip is designed to hydroplane over pre-lubricated surfaces in order to provide extreme low friction and excellent wear resistance.
